Finally, ear length at 11-14 wk of gestation has been evaluated in screening for chromosomal defects but the degree of deviation from normal is too small for this measurement to be useful as a marker for trisomy 21 [ 51 ]. An echogenic intracardiac focus is a hyperechogenic spot (aka bright spot) that is seen on a baby's ultrasound in utero; the most common location of this "bright spot" is the left ventricle of the heart.

They are of two types histopathologically. Ultrasound diagnosis: Single or multiple cystic areas (>2 mm in diameter) in one or both choroid plexuses of the lateral cerebral ventricles. Subependymal cysts due to small germinal matrix hemorrhages are a major differential diagnosis. On an ultrasound, areas with more calcium tend to appear brighter. Surgical treatment should be considered in the case of signs of increased intracranial pressure and compression of neural structures.
